FLUSHING-TANK VALVE.

Specification of Letters Patent.-

Patented July 6, 1909.

Amincaaon med June 11, 190s. serial No. 437,969.

waukee, in the county of. lililwaukee and State of lliseonsin, have invented certain new' and useful Improvements 1n Flushing- Tank Valves; and l do declare. the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

)dy invention relates to improvements in valves for .rater closet flushing tanks.

lt has forits object to provide for the prznitieally `noiselrss inlet of .vafer to the tanks-and to carry out said purpose in an ell'eetivc and reliable manner as well as to efl'ect the automatic stoppage of the 'flow ofI the water into the tank.

`With these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement olE partsv as v-ill be described and particularly oomied out in the appended claims.

In the accompany ing drawing, illustrating the preferred embodunent of my invention,

thc 'figure represents a vertical sectional elevation thereof', partly in side view.

ln carryingr out myinvention I suitably provide the flushing tank with a valve, 1, comprising'a tubular threaded shank member 2 forming the lower portion of the valve casing,va dome-like. member I forming the npperpart of the easing, an elastic or resilient diaphragm, 4, and the valve member i proper, 5, all assembled, preferably as disand suitably bolted thereto.

closed, said diaphragm beine,` interposed between the members, 2 and 3 ol' the casing, 'l`he valve member proper, 5, ulrich has a disk-like lower portion resting upon the diaphragm, 4, has its stem portion extending upwardly through a tubular extension, (i, of' the member, In. The diaphragm, 4, has its lower surface arranged directly above and inwardly spaced ofi from a broad, annular portion having a corresponding depressed or eoneaved extension, 7, provided with numerous ports, S, for the. passage of the water from the shank member 2 of the casing, into the. flushing tank.

The shank member of the casing, 2, has screw threaded connection with a sleeve or additional tubular member, 9,

through the bottom of the iushing tank, saiil member 9 having its upper end provided with exten din (f a flan ge 10, resting upon the upper surface of said tank bottom, said member l) also having an external screw threaded portion equip )ed with a lock nut, 11, for Securing?r said mem )er t) in effective position. Said member 9 has also coupled lo its lower receiving end what may be termed a tail piece, 12, as usually employed in this connection, the coupling between said member and the latter being cfi'ectcd by'means of a collar or nut, 13.'

A lever, 111, )referably ot inverted U-shape, has one end thereof pivoted to an upstanding portion 3 of the member 3, while eX- tending;I horizontally from the opposite end of said lever 1-1 is a terminal,\15. baid lever, 111, is` provided with an adjusting or regulating' screw, 16, adapted to engage the upper end oll the valve stem for controlling or predeterminingr the shutting-oil point for the inflow of water, as will bo r iadily appreciated.

i' lever, 17, having one ond novided with a spherical enlargement or ball, 1S, and adapted to rise with the inflow of water, is )ivoted to a bracket or arm, 19, of' the member, Il, and has its inner end adapted to engage terminal of the lever, 14, as in electing` the closing' operation of the valve.

lt will benotcd that the valve seat, 7, bel ing ol' broad area and devoid of any angular edges or portions, the action of the valve in cfl'ecting contact between the diaphragm, 4, and said seat, will be practically noiseless, as is greatly desirable in this class of devices, as will he readily understood.

In operation it will be seen that in filling' the tank with water, as the latter is received into said tank through the pipe .1, and inlet portion of the valve seat, the water will flow through the ports, S, and enter said tank, and as the water continues to rise therein, the

float, 1S, of the lever, 17, will accordingly rise therewith, inclining the inner end ol' said lcver downwardly toward and into engagement with the terminal,.15, of the lever, 14. This action will cause the lover, 14, whose set or thumb screw, 16, is in engagement with the stem of" the valve, 5, to descend and accordngly depress said valve upon the diaphragm, 4, which will causerthe latter, finally, according to the height ofthe water in the tank, to

engage the valve seat and shut oil the inflow of further water, as re( uired.

It will be seen from tllie foregoing arrangement of parts that a very simple and effective device is provided for the aforesaid purpose; and one which, stated, is practically Various changes in the form, proportion details of construction may be from the prinadvantages of appended and the minor resorted to without departing ciple or sacrificing any of the the invention as deined in the claims.

Having thas described my invention, what i claim as new and desire to secure by Letters-Patent is:

. l. A 'de vice of the character described comprising a valve and stein for the saine, a casing consisting of a shank member provided with a valve scat and a dome-like inember carrying the valve, an elastic diaphragm for engagement with said scat, a lever of approximately U-shaped outline equipped with l i l l l l l l l l,

means for engagement with the valve stem and a float equipped lever adapted to engage the aforesaid lever.

2. A device olE the character described, comprising a tank or inclosure, a casing consisting of a shank member provided with a valve seat and a dome-like member, a valve arranged in the valve casing, a stem'for the valve, an elastic diaphragm interposed between said valve and the seat portion of said4 casing, a lever over-hanging said valve and valve casing and provided with a regulating or controlling screw, and a float equipped lover having' one end adapted to engage a terminal, of the aforesaid lever.

In testimony whereof I have hereunto set my hand in presence of two subscribing' Witnesses.
